Penfold v The Queen

The appellant, Penfold, was convicted of aggravated break, enter and steal and appealed against the conviction and sentence. The appeal was heard in the High Court of Australia. The appellant contended that the trial judge erred by failing to discharge the jury after learning that some jurors perceived the appellant to threaten a witness from the dock and by refusing an application to discharge the jury due to concerns about juror impartiality. Additionally, the appellant argued that the evidence upon which the case against him depended was problematic and that the verdict was unreasonable or unsupported by the evidence.

The court considered whether the trial judge's failure to discharge the jury was erroneous and whether the identification evidence was problematic. The court found that the trial judge's direction to the jury to disregard the perceived threat was inadequate and that a fair-minded and informed observer would have apprehended a lack of impartiality by the jurors. The court held that the trial judge's refusal to discharge the jury was erroneous and that the failure to do so tainted the trial. Regarding the identification evidence, the court found that it was problematic for several reasons and that the verdict was unreasonable or not supported by the evidence.

The court allowed the appeal and quashed the conviction. The court held that the trial judge's failure to discharge the jury due to perceived juror bias and the problematic identification evidence resulted in a tainted trial. The court found that the appellant's conviction was unsafe and unsatisfactory, and the appeal was allowed. The conviction was quashed, and the appellant was acquitted of the charges.
